Potentilla plant named &#39;smnpps&#39;

ABSTRACT

A new and distinct Dasiphora cultivar named ‘SMNPPS’ is disclosed, characterized by large, single pink flowers on round, compact plants. The new variety is a Dasiphora normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Dasiphora fruiticosa.

Variety denomination: ‘SMNPPS’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety of Dasiphora hereinafter referred to by the cultivar name. ‘SMNPPS’ This new Dasiphora was developed through a breeding program in Grand Haven, Mich. The objective of the breeding program was to develop new Dasiphora in new colors, and larger flowers. ‘SMNPPS’ is an internal advanced selection from an in-house breeding program. The open pollination date resulting in the new variety was in 2011. Selection of the new variety was made during 2014.

The first asexual propagation of ‘SMNPPS’ was carried out during 2014 by softwood cuttings at a poly greenhouse in Grand Haven, Mich. ‘SMNPPS’ has been found to retain its distinctive characteristics through successive asexual propagations. Multiple generations have been propagated, with the new variety characteristics reproduced true to type.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under standard horticultural practices at Grand Haven, Mich.

-   -   1. Large, single, pink flowers.     -   2. Round, compact plant.

COMPARISON WITH THE PARENT VARIETY

‘SMNPPS’ is similar to the seed parent Dasiphora fruticose ‘Pink Dbl 2F2’, in most horticultural characteristics. ‘SMNPPS’ however differs in the following:

-   -   1. New variety has single flowers, the seed parent has double         flowers.

COMMERCIAL COMPARISON

‘SMNPPS’ is similar to the commercial variety Dasiphora fruticosa ‘Kupinpa’, U.S. Plant Pat. No. 22,732, in most horticultural characteristics. ‘SMNPPS’ however differs in the following:

-   -   1. Plants of the new variety produce single flowers, this         comparator produces semi-double flowers.     -   2. Flowers of new variety have pink edges, fading to white         towards center. Comparator's flowers have very pink petals from         edges to center.

DESCRIPTION OF THE PHOTOGRAPHS

This new Dasiphora is illustrated by the accompanying photographs which show the plant's form, foliage and inflorescences. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. Plants were grown in Grand Haven, Mich.

DESCRIPTION OF THE NEW CULTIVAR

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2015 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SMNPPS’ plants grown in a poly-greenhouse during Summer, in Grand Haven, Mich. USA. The growing temperature ranged from 18° C. to 27° C. during the day and from 5° C. to 10° C. during the night. General light conditions are natural sunlight. Measurements and numerical values represent averages of typical plant types.
